STATIONARY FILTER TYPE SUCTION CLEANER Filed July 16, 1947 3 Sheets-Sheet 5 I Snventor WILLIAM l. GAGE (IttornegS Patented Sept. 20, 1949 STATIONARY FILTER TYPE SUCTION CLEANER William I. Gage, Lakewood, Ohio Application July 16, 1947, Serial No. 761,368

The present invention relates to a stationary filter type suction cleaner and has for its object the provision of a self-contained suction cleaner of the bagless type.

The present invention contemplates a completely self-contained suction cleaner in which all of the .operating parts of the cleaner and the dust or dirt compartment are enclosed within a unitary housing.

It is a further object of the invention to provide a unitary suction cleaner construction that is light in weight and susceptible of easy portability; particularly when used in combination with the suction attachments therefor.

More specifically, the invention contemplates a suction cleaner embodying a unitary housing embracing a longitudinally extending cylindrical filter and motor operated means for insuring relative movement between the cylindrical filter and a device for maintaining the filter free from dirt.

Further and more detailed objects of the invention will become apparent as the description proceeds, which will be given in connection with the accompanying drawings forming a part hereof and in which:

Figure 1 is a longitudinal sectional view through the cleaner housing disclosing the relationship of parts therein;

Fig. 2 is a fragmentary bottom plan view illustrating the suction nozzle and associated elements;

Fig. 3 is a cross sectional view on the line 3-4 of Fig. 1;

. Fig. 4 is a fragmentary side elevational view of the front end of the suction cleaner disclosing the manner of application of a suction attachment thereto;

Fig. 5 is a detailed sectional view of the adjustable front roller mounting; and

Fig. 6 is a fragmentary cross sectional view on the line 6-6 of Fig. 5.

Referring to Figure 1, the suction cleaner housing is indicated generally at l and is provided with rear caster wheels I I and a vertically'adjustable transversely extending front roller l2. The housing I!) has a streamline upward extension l3 provided with hand hold opening l4 and with transverse openings I for the attachment of a shoulder strap diagrammatically illustrated at I6-|1. The housing I5 is also provided with a suitable detachable elongated handle l8 adapted to be attached to the housing as indicated at IQ for use when the suction cleaner is to be pushed over the floor. A suitable extension cord 20,

(0]. 183-52) having a plug 2| and embracing a conventional 55 switch 22, supplies current for the motor 23 and for the headlight 24, so positioned as to light up the floor in advance of the suction cleaner. The plug 2| and the headlight 24 are mounted in a curved streamline pivoted front section 25 of the housing In which is adapted to be moved into the dotted line position of Figure 1 about the pivot point 26.

The housing Ill terminates at its forward end in a laterally flared portion having the lower wall 21 and the upper wall 28 to provide therebetween a suction nozzle extending transversely of the suction cleaner. The upper wall 28 of the suction nozzle has secured to the rear end thereof a partition member 29 secured to the wall 28 through the medium of appropriate screws such as 30. The partition member 29 extends vertically through the housing and is afiixed at its upper end to a rigid flange 3| carried by the housing ID. The arrangement is such that the partition 29 forms a wall separating the motor from. the path of dust and dirt laden air moving through the suction cleaner. A motor supporting bracket 32 is afiixed to the partition wall 29 and supports the motor 23 through the motor supporting bracket 33.

The rear Wall of the housing I0 is provided with a plurality of openings 34 through which the" dust free air is expelled from the suction cleaner. The housing 10 is additionally provided with an integral transverse partition member 35 at the rear end thereof, to the lower rearmost portion .of which the door 36 of the dust and dirt compartment 3'! is pivoted as indicated at 38. The door 35 is adapted to be held in closed position by the retractable latch 39. The transverse partition 35 carries at its forward end a circular plate 40 which is welded or otherwise suitably secured to the transverse partition 35 as indicated The circular plate 40 is formed with a central depression 42 for receiving the race of the ball bearing 43. The circular plate 40 is flanged around its periphery as indicated at 44. The housing ID is provided with an inwardly extending annular flange 45. A cylindrically formed filter screen 46 is attached at one end throughout its circumference to the flange 45 as indicated at 41. The opposite end of the screen 46 has its lower portion cut away as indicated at 48. and the remainder thereof secured to the flange 44 of the circular plate 48. The arrangement is such that the cylindrical filter screen 46 is held stationary in the housing in. The cut away portion of the filter screen 46 is indicated at 48 and communimotor 23.

cates with the dirt receiving chamber 31 at the lower rear portion of the housing 10.

The motor shaft 48, it will be observed, extends both forwardly and rearwardly from the This motor shaft 48 passes through and is partially supported by the partition wall 29 and extends centrally through the stationary cylindrical filter 46 and has its extreme rear end 49 received in thejball bearing 43 positioned in the central recess 42 of the stationary circular plate 46. The motor shaft 48 rotates freely with- V in the ball bearings 43-. A helical conveyor element 56 having the hub 5| is rotatablymounted,

on the motor shaft 48. helical conveyor member 56 is rigidly secured to the circular plate 52 having the internally toothed flange 53 which provides what maybe.

A small gear '54 is The rear end of the v conveyor '56.

achieved through the reduction gears 54, and

53. The blades of the helical conveyor 50 term inate in close juxtaposition to the stationary cylindrical filter 46, as indicated at 56, so that any dirt collecting on the interior wall of the cylindrical filter 46 is constantly. removed therefrom and carried by the helical conveyor 50-.to the opening 48 in the lower rear portion of the cylindrical filter 46 and discharged therethrough into the dirt receiving chamber 31.

The suction inducing fan 51 is mounted on the motor shaft 43 intermediate the forward end of the helical conveyor element 50 and the parti" tion member 29. The arrangement is such that the suction inducing fan 51 rotates" at the speed of rotation of the motor shaft 48. A small fan 56 is mounted forwardly of the motor 23 on-the motor shaft 48 for the purpose of effectively cooling the motor 23. Itwill be observed by reference to Fig. 4 that the front portion of the housing i6 is vented as -indicated at 59 to admit the circulation of coolingairfor the motor 23. A rotatable sweeper brush 66 extends transversely of the suction cleaner and is mounted for rotation in the suction'nozzle provided between the walls 2? and 28. The rotating sweeper brush 66 is driven by a belt 6| trained over .the forward end of the motor shaft 48 between the fan 58 and the end thereof to thus provide, a positive drive for the sweeper brush 6!). The ends of the sweeper brush 66 are supported'in appropriate vertically adjustable bearings, not shown, through the medium of screws 62 (Fig. 2). V

The rotatable roller I2 has its ends supported in vertically adjustable bearings 63 mounted on screws 64, as more particularly illustrated in Fig. 5. Slightly to the rear of the front roller l2 and intermediate that roller and the transverse suction slot in which the rotating brush is mounted, the lower wall 65 of the housing l6 (Figs. 2 and 6) is provided with a series of openings 66 arranged transversely of 'the suction cleaner. Just above the series of openings 66 there is mounted a roller 61 extending transversely of the suction cleaner and provided along its "periphery with a longitudinally extending groove 68. The roller'61 is driven by frictional contact with the fioor contacting roller l2. The arrangement is such that-the groove 68 of the grooved roller 61 and the openings 66, acts to loosen the dirt in the carpet and to raise the nap so that the sweeper'brush 60, acting in cooperation with the suctioninduced through the medium of the fan 61, effectively frees the rug or carpet of the dirt which follows the path of the arrows shown in Figure 1. Specifically, the

'dust laden air moves past the fan 51 and into the helical path around the blades of the helical The dust and dirt are collected on the innenwallof the stationary cylindrical filter 46 and the dust free air passes out through this filter into the annular space surrounding the same and thence past the circular plate 46 above the .transversepartitlon 55 and is expelled through the openings 34 in the rear of the housing. 4

In this operation the motor 2| drives the" motor cooling fan 58 and the suction inducing fan 51. It likewise drives the helical conveyor 56 through the reducing gears 54, 55 and 53'. The speed of rotation. of the helical conveyor'56 is determined by the ratio of said reducing gears. Likewise, the motor 23 drives the rotating sweeper brush 66 through the medium of the belt. 6|. Thebladesof the helical conveyor 50 substan tially contact the cylindrical filter 46 and keep the same free from any accumulation of'dust and-dirt, the latterbeingadvanced by the helical conveyor and dischargedinto the dust receiving compartment 31 from which it may be removed at Willby opening the door 3-6 thereof. 7 L

. Normally, when the suction cleaner is being employed for, the. cleaning of carpetarugs and the ing upholstered furniture, walls and the like, the

closure plu 65 is removed'from the opening '16 and an attachment couplin M (Fig. 4) is inserted in the opening 16 in place of the plug" 69. The attachment coupling l! is provided with a bifurcated extension l2'that is adapted to pass'down around the motor shaft 48 and substantially close off the passageway between the walls 21 and 28 of the suction nozzle to thereby cause the suction inducing fan 57 to impose its primary suction on the attachment 13.

Inasmuch as the'suction cleaner is extremely compact and light in structure it can be carried on the shoulder of the operator through the medium of the attaching strap l6--I l and this facilitates its use in association with various attachments conventionally employed in the suction cleaner art. Having thus described my invention, what I- claim is:

l. A suction cleaner of the baglesstype comprising a housing, a motor mounted'in the hous ing, 3. motor shaft extending longitudinally of theiheusing, a stationary cylindrical filter surrounding the motor shaft, a rotatable helical filter cleaning blade mounted on'the motor shaftinteriorly of said stationary filter, and means'for driving said filter cleaning blade from said motor shaft.
